Step

Download the MongoDB MSI Installer Package

Choose the package you want.

Set up Folders

Planning cluster nodes

A config replica set ( 3 replica nodes, without arbitration node )
Two shard replica set ( each of them has 2 replica nodes + 1 arbitration node )
A mongos node

datas folder

config folder ( config1, config2, config3 )

shard folder - the same as config

mongos folder

Tips:

Pay attention to the difference between mongos and mongod

Configure nodes

Port plan

shard-a:               shard-b:               config-a:               mongos:6000
    shard-a1:3001          shard-b1:4001           config1:5001
    shard-a2:3002          shard-b2:4002           config2:5002
    shard-a3:3003          shard-b3:4003           config3:5003

Configure shard nodes

Edit mongod.cfg in each shard directory and change dbpath, logpath, port and replSet to the corresponding values

dbpath=E:\mongodb\datas\shard-a1\data
logpath=E:\mongodb\datas\shard-a1\log\mongod.log
logappend=true
directoryperdb=true
rest=true
httpinterface=false
port=3001
shardsvr=true
replSet=shard-a

Configure config nodes

Edit mongod.cfg in each config directory and change dbpath, logpath and port to the corresponding values

dbpath=E:\mongodb\datas\config1\data
logpath=E:\mongodb\datas\config1\log\mongod.log
logappend=true
directoryperdb=true
rest=true
port=5001
configsvr=true
replSet=config-a

Configure mongos node

Edit mongos.cfg in mongos directory

configdb=config-a/hostname:5001,hostname:5002,hostname:5003
logpath=E:\mongodb\datas\mongos\log\mongos.log
logappend=true
port=6000

Host all nodes on Windows Service

Open the Command Prompt with Administrative Privileges

All shard and config nodes ( modify the service name and .cfg file path )

sc create MongoShardA1 binPath= "E:\mongodb\bin\mongod.exe --config=E:\mongodb\datas\shard-a1\mongod.cfg --service"
net start MongoShardA1

mongos node

sc create MongoRouter binPath= "E:\mongodb\bin\mongos.exe --config=E:\mongodb\datas\mongos\mongos.cfg --service"
net start MongoRouter

You can use netstat -nao command to check

Configure shard and config replica set

Switch to bin path location of the MongoDB files installed
Connect to any node in the shard-a
Initialize the replica set
Add the other two members of the replica set, a replica node and an arbitration node
You can use rs.status() to check the replica set status

mongo --port 3001
rs.initiate()
rs.add("hostname:3002")
rs.add("hostname:3003",{arbiterOnly:true})  # config: rs.add("hostname:5003")
rs.status()

shard-b and config-a are same to configure the replica set, the difference is that the config replica set does not need to specify an arbitrator node.

Add shard

Switch to bin path location of the MongoDB files installed
Connect to mongos node
Use sh.addShard to add sharded replica set for Router
Use db.getSiblingDB(“config”).shards.find() to check

mongo --port 6000                                
sh.addShard("shard-a/hostname:3001,hostname:3002,hostname:3003")
sh.addShard("shard-b/hostname:4001,hostname:4002,hostname:4003")
db.getSiblingDB("config").shards.find()

Enable shard on database

Use sh.enableSharding(“dbName”) to enable shard on database
Use db.getSiblingDB(“config”).databases.find() to check

sh.enableSharding("testdb")            
db.getSiblingDB("config").databases.find()

Slice Collection

Define a slice key ( you can use only one field as the slice key, or use a combination of slice key: sh.shardCollection(“dbName.collectionName”,{key1:1,key2:1})
Use db. getSiblingDB(“config”).collections.find() to check

sh.shardCollection("testdb.testform",{_id:1})  # use _id to slice
db.getSiblingDB("config").collections.find()

Verify: Insert a large amount of data

use testdb                              
for(i=0;i<1000000;i++){db.testform.insert({Uid:i,Desc:"This is a test data",Data:new Date()})}
mongo --port 6000   
sh.status()

You can see that the data is allocated to two slices for storage.
